Lights beamed from the Back Bay last night in celebration of the groundbreaking of a new neighbor for the Pru and the Hancock Tower—the much-anticipated Four Seasons Hotel & Four Seasons Private Residences at One Dalton Street. The triangular tower will be built on land at the edge of the Christian Science Plaza. At 61 stories and 699 feet, it’s set to be the tallest building constructed in New England since the early 1970s, and the third tallest on the Boston skyline.

Developed by Carpenter & Company, Henry Cobb of Pei Cobb Freed, known for his design of the John Hancock Tower, and Gary Johnson of Cambridge 7 Associates are the lead designers behind the $750 million project.

On the lower 23 floors, the new Four Seasons Hotel will include 211 luxury rooms, two restaurants, two lounges, and a health club and spa. With that, Boston will join an exclusive list of cities—including London, Shanghai, Singapore, Los Angeles, Chicago and Istanbul—that are home to more than one Four Seasons hotel.

Accessible through a separate entrance, floors 25-61 will include 180 private residences with unobstructed views in all directions. Residences will feature 11-foot ceilings, bay windows, concierge and doorman services, and a private restaurant club on the 50th floor. Campion & Company will serve as the sales agent for the private residences, with pricing set to be announced this spring.

Mayor Martin J. Walsh called One Dalton Street a signature project for Boston—not only will it be the tallest building in decades, but it redefines high-end residential living and will have a positive impact on the economy, with 1,500 construction jobs, 450 permanent jobs, and increased tax revenue to the city.

The general contractor for the project is Suffolk Construction Company, and construction is expected to last two-and-a-half years.
